Definitions

  • This invention relates to medical diagnostic imaging systems and methods.
  • each modality of diagnostic medical imaging equipment such as Computed Tomography (CT), X-ray, Nuclear Medicine and Magnetic Resonance Imaging (MRI)
  • CT Computed Tomography
  • X-ray X-ray
  • MRI Nuclear Medicine and Magnetic Resonance Imaging
  • object handling systems generally included a table disposed over a base. The top side of the table is used to support an object, such as a patient, for imaging.
  • the mechanical configuration of the imaging equipment to which each object handling system is mated often affects the configuration and features for each type of object handling system.
  • CT and MRI imaging equipment generally have gantries that form imaging spaces. These imaging spaces are generally horizontal to the floor and often have part of the gantry disposed between the imaging space and the floor.
  • the table and base can be disposed between the source of radiation and the floor and the table can remain over the base.
  • Another imaging equipment feature that affects the object handling system configuration is the height of the imaging space from the floor. For example, if the height of an imaging space for a CT is different from the height of an imaging space for an MRI, the height of the object handling system associated with each system must be adjusted accordingly.
  • the physics of a specific imaging modality configuration also affects, in part, the features of an object handling system.
  • tables designed for use exclusively in an MRI environment are made from fibreglass composites.
  • tables designed for use exclusively in radiation transmissive modalities, such as x-ray and CT are preferably made from carbon composites.
  • the selection of a fibreglass or carbon composite table is motivated, in part, by a desire to minimize the effect of the table on the imaging modality with which the table is being used.
  • a table movement means such as a motor, is often used to extend the table relative to the base and into the imaging space.
  • object handling equipment used with x-ray and Nuclear Camera equipment the table often remains fixed over the base during imaging and the x-ray source and Nuclear Camera equipment are moved relative to the fixed table.
  • more than one object handling system having different features is often available depending on the type of imaging to be performed and the desired object handling system features.
  • some object handling systems have a tilting feature that allows the table to be tilted from horizontal to vertical.
  • Other object handling systems have a table that "floats" on the base thereby allowing the table to be moved in one or more directions in a horizontal plane.
  • Still other tables may only have a top fixed at one position over the base.
  • a drawback to having a dedicated object handling system for different modalities of diagnostic imaging equipment or different imaging equipment of one modality is that the patient must be moved to each object handling system for imaging by the respective imaging equipment.
  • the patient is often disposed on a transportation gurney for movement into and out of an imaging room. Once in the room the patient is moved from the gurney to the object handling system to be imaged. After the imaging procedure is complete, the patient is returned to the gurney and transported out of the imaging room.
  • One drawback to this arrangement is when the patient is being sequentially imaged on two or more diagnostic imaging equipments, it is necessary to move the patient between the gurney and the object handling system and back again for each imaging equipment the patient encounters.
  • Another drawback to this arrangement is that if the patient is unable to assist in moving between gurney and object handling system, two or more medical personnel may be needed to move the patient each time resulting in inefficient use of such personnel whose time and talents may be more effectively used elsewhere.
  • an object handling system is generally associated with a specific imaging equipment. Thus, if a feature of the object handling system is inoperative, such as the table movement means used to extend the table relative to the base and into the imaging space of a CT or MRI, the ability to use the imaging equipment is affected.
  • the imaging equipment e.g., CT and MRI
  • the imaging equipment has one or more detectors for receiving imaging information from the patient.
  • the received imaging information is converted to electrical signals by the detectors.
  • These electrical signals are processed by an imaging computer and converted into viewable images of the patient's anatomy.
  • Data regarding the identification of the patient is often entered into the imaging computer, via a keyboard, for association of the viewable images with the patient identification data.
  • This patient identification data may include, for example, name, sex, date-of-birth, social security number, insurance information, examination specific information, e.g., technique factor, slice number, and the like.
  • Moving a patient from one imaging equipment to another requires this patient identification data to be entered into the computer of each imaging equipment so that a correlation between the patient being imaged and the resultant images is achieved.
  • Drawbacks of having to enter patient data more than once is the time required to enter such data at each imaging equipment and the potential for operator entry error during multiple data entries.
  • One way to overcome these drawbacks is to have a computer network connecting the various imaging equipments whereby the patient data can be entered once and retrieved at each imaging equipment.
  • a drawback to the computer network is that the patient being imaged must be accurately identified at each imaging equipment. If the patient is incorrectly identified, improper correlation between the patient and the resultant images can occur.
  • the present invention provides an improved object handling system that overcomes the above problems.
  • a medical diagnostic system comprising: a diagnostic imaging equipment of a first type for producing a first diagnostic image of an object; a diagnostic imaging equipment of a second type for producing a second diagnostic image of the object, said first and second imaging equipment having respective first and second imaging computers for controlling the production of images thereby, said first and second imaging equipments having respective first and second imaging spaces; and an object handling system for use in supporting said object during examination comprising: a table for supporting the object during examination; a base for supporting said table above a floor; a computer for storing data relating to the identification of the object under examination; and means for selectively linking the object handling system computer to one of the first and second imaging equipments, said linking means providing a data communication path between the object handling system computer and the computer of the selected one of the first and second imaging equipments such that said identification data is available to the computer of the selected one of the first and second imaging equipments for use in the production of diagnostic images.
  • the linking means includes a means for securing the base to at least one of the first and second imaging equipments.
  • At least one of the first and second imaging computers stores positioning data relating to the relative position of the table and the respective imaging space necessary for object examination, said data communication path allowing said positioning data to be available to the object handling system computer for use during the production of diagnostic images.
  • a method of diagnostic imaging an object using first and second diagnostic imaging equipments comprising: disposing the object on a movable object handling system having a table disposed over a base; docking the object handling system relative to the first imaging space; producing diagnostic images of said object with the first imaging equipment; undocking the object handling system; moving the object handling system, with the object disposed thereon, to the second imaging equipment; docking the object handling system relative to the second imaging space; producing diagnostic images of said object with said second imaging equipment; entering object identification data into a data storage means disposed on the object handling system prior to producing diagnostic images of said object with one of the first imaging equipment and the second imaging equipment; connecting said data storage means to said one of the first imaging equipment and second imaging equipment prior to producing diagnostic images therewith; and associating said data with the images of said object produced by said one of the first and second imaging equipments.

  • Imaging equipment there is one diagnostic imaging equipment per room.
  • the choice to have one diagnostic imaging equipment per room is dictated, in part, by a desire to maximize the availability of the imaging equipment.
  • imaging equipment of two different types eg, an Angio type x-ray equipment and a CT equipment
  • One such application includes precisely positioning a catheter in a patient using an Angio equipment and then introducing a pharmaceutical into the patient via the catheter while the patient is being imaged by a CT system. In this case, it is desirable to move the patient between the respective imaging equipment as quickly and efficiently as possible so as to not disturb the catheter position and to minimize patient discomfort.
  • a CT equipment 104 eg, as described above with reference to Figure 1
  • an Angio equipment 108 and an object handling system 112 as described above with reference to Figures 1 to 4 are disposed in room 114.

  • the orientation of the object handling system 112, with patient disposed thereon, is changed such that the table is disposable into the imaging space 128 of the Angio equipment 108.
  • This change in orientation is accomplished by moving the object handling system 112 on the wheels 28 as set forth above in conjunction with the discussion of Fig. 1.
  • the base may be disposed on pivot 134 that allows the table to be pivoted between the CT equipment 104 and the Angio equipment 108.
  • the operation of the table movement means 50 and/or the height adjustment means 42 is selectively controllable as a function of the orientation of the object handling system to the Angio equipment or CT equipment.
  • the object handling system 112 is used in two different manners depending on whether the handling system is used with the CT equipment or the Angio equipment. Specifically, when used in conjunction with the CT equipment, it is desirable for the table movement means 50 to move, or index, the table into the imaging space of the CT equipment in coordination with the production of diagnostic images. In contrast, when used with the Angio system, it is desirable for the table to "float" on the base such that an attending physician can manually move the table thereby controlling the position of the patient in the imaging space of the Angio equipment. To facilitate the floating top, the table movement means 50 is not energized when the table is used with the Angio equipment. Alternatively, a means for selectively engaging the table movement means 50 to the table 132 may be provided.

  • at least one of patient identification data and imaging data are entered into the object handling computer 34 via the second data entry means 36.
  • the facility has a connector (not shown) connected to a hospital computer (not shown), used to record information about patients such as admission time, insurance carrier, treatment, and the like.
  • the hospital computer connector is not rigidly attached to a housing but rather is at the end of a flexible harness to allow the connector and the object handling system connector 32 to be joined without having to orient the object handling system in a specific direction.
  • the object handling system B When the patient is ready to be imaged, the object handling system B is docked to an imaging equipment, such as equipment A described above, and at least one of the patient identification data and imaging data are transferred from the object handling computer 34 to the imaging computer 12 for use in the production of images by the imaging equipment associated with the imaging computer 12.
  • An advantage of using the object handling system B in this manner is that during transportation, patient identification data and/or imaging data is entered into the object handling computer 34 thereby enhancing the efficiency of admission to the hospital.
  • the object handling system B and specifically the table 26, is preferentially comprised of different materials at opposite ends of the table.
  • tables used with MR imagers are commonly made from a fiberglass composite that includes strands of fiberglass held together by an epoxy resin.
  • tables used with x-ray or CT imagers are commonly made from a carbon composite that includes carbon and epoxy.
  • the table 26 is comprised of different materials at opposite ends of the longitudinal axis of the table.

  • the first connector and second connector are replaced by r.f. or optical transceivers.
  • Using an r.f. or optical communication transceiver avoids the need to physically connect the first connector 18 and second connector 32.
  • the r.f transceiver may be useful in transferring patient identification data and/or imaging data from the ambulance to the hospital, clinic or other such facility prior to arriving at the hospital, thereby further enhancing admission of the patient at the facility.
  • a clamp means 150 is secured between the base of the object handling system and the floor.
  • the clamp means is comprised of a first horizontal plate 152 secured to the floor, a vertical plate 154 connected to and extending upwards from the first plate and a second horizontal plate 156 attached to the vertical plate and extending over and engaging a portion of the base.
